Abstract
    M. scolopax is a euryphagous fish. Diet consists mainly of crustaceans (80,4 p. 100 by number, 61,73 p. 100 by frequency and 87,58 p. 100 by weight). Preferred prey are Paguridae (Anapagurus laevis dominating) and, some way behind, Polychaeta. Amphipoda are secondary prey, and the remaining groups, accidental. Almost all the Paguridae are eaten by specimens over 128 mm, with the Polychaeta and Amphipoda more frequent in specimens under this length. M. scolopax feeds almost exclusively on benthic prey: pelagic prey frequency is under 10 p. 100. Clear-cut differences between the Atlantic and Mediterranean feeding habits, of this species, are also shown.
